ADJUSTABLE BEARING.

Specification of Letters Patent.

Patented 0011.20, 1914.

To aZZ whm it may concern:

Be it known that we, HERBERT S. AS and EMET H. HAYES, citizens of theUnited by continuous usage,

States, residing at Knoxville, in the county of Knox and State ofTennessee, have invented certain new and useful Improvements inAdjustable Bearings; and we do hereby declare the following to be afull, clear, and exact description of. the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to bearings for power shafts and the primaryobject of the same is the provision of a bearing embodyingsliding-bearing blocks, which are easily interchangeable or removablefor replacement of a new box, and a vertically and laterally adjustableshoe associated with the bearing box support, for supporting the shaftwhen the bearing boxes become worn while the bearing blocks are beingchanged.

\Vith the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference designatelike or corresponding parts throughout the several views, and in whichFigure 1 'is a side elevation of the improved bearing box. Fig. 2 is acentral sectional view through the improved bearing box, and Fig. 3 is across sectional view on the line 33 of Fig. 2.

. Referring more particularly to the drawings, 1 deslgnates the bearingbox as an entirety, which hasits outer shell 2 supported in, anysuitable manner, and being provided with the rectangularly shaped bore 3extending longitudinally therethrough. The

- rectangularly shaped bore 3 has removably, or slidably seated thereinthe two bearing blocks 4 and 5, which blocks have their sides lying infacial abutment with the edges or sides of the bore 3, and have theirinner meeting faces provided with semi-circular" recesses 6 and 7, whichreceive and form a bearing for the power shaft 8. The hearing blocks 1and 5 have reetangularly shaped bosses 9 and 10 formed upon their outersides, which bosses are inserted in the friction shoes 11 and 12 whenthe bearing blocks 4: and 5 are properly positioned within the bearingshell 2. The friction shoes 11 and 12 are adjustably held within therectangular bore 3 of the shell 2, by thumb screws 13 and 141, whichthumb screws are seated in re cesses 15 formed in the bosses 16, whichbosses are formed upon the outer faces of the friction shoes 11 and 12The friction shoes 11 and 12 have recesses formed in their inner facesfor the reception of the bosses 9 and 10, and by adjusting the shoes 11and 12 by the thumbscrews 13 and 14, the shoes may be firmly held inengagement with the lugs 9 and 10, to hold the bearing blocks 4 and 5rigidly and securely in the proper position for forming a bearing forthe shaft 8. The bore 3 of the shell 2 is provided with recesses 18 forthe reception of the bosses 16, to permit of the' proper adjustment ofthe shoes 11 and 12, so that they may be moved out of engagement withthe bosses 9 and 10, to permit of the sliding removal of the bearingblocks 4 and 5 from the interior of the shell 2. y

The shell 2 has formed-thereon, :1 lug 20, which lug is centrallypositioned on the vertical radius of the shell 2 and is provided I withan opening 21, whiohiopening forms a guide-way for the sliding bar 22.The lug 21 has an arm 23 formed thereon, which arm is spaced from theperiphery of the shell 2, being bent inwardly and communieating with theshell at its inner end, as is shown at 24.

The arm 23 has a set screw 25 adjustably carried thereby, which setscrew is provided for the purpose of holding the sliding bar 22 invarious adjusted positions, having its inner end abutting one surface ofthe bar and binding it within the guide-way formed in the lug 20 and theinner side of the guideway formed between the arm 23 and the surface 26which is formed upon the shell 2 rearwardly of the lug 20. The flatsliding bar 22 has its end 27 enlarged and provided with a screwthreaded sleeve 28, which sleeve has adjustably mounted therein a screwmember 29. The screw member 29 has a saddle 30 rigidly mounted upon itsupper end, and the saddle 30 is positioned, so as that upon adjustmentof the screw member 29, the saddle maybe moved vertically, forsupporting engagement with the power shaft 8, and the shaft maybe alinedby adjustment of the screw member 29,

when the shaft is seated within the saddle 30.

When the bearing blocks 4 and 5 become Worn so as to render the bearingsim perfect and cause improper rotation of the power shaft 8, the shoe 30may be moved upwardly so that it will receive the shaft 8 in thesemi-circular bearing surface formed between its arms 31 and 32, afterwhich the thumb screws 13 and 14 are adjusted so as to move the frictionshoes 11 and 12 out of engagement with the rectangular bosses 9 and 10,to permit of the sliding removal of the bearing blocks 4: and 5 from theinterior of the shell 2, so that they may be replaced with new bearingblocks without hindering or stopping the operation of the machine ormachinery which are propelled by the power shaft 8.

In practical fields certain minor features of construction,and'arrangement of parts may necessitate alterations to which thepatentees are entitled provided such alterat1ons are comprehended Withinthe scope of what is claimed.

hat we claim is 1; In a bearing for rotary shafts, a bearing supportingshell having bearing blocks slidably seated in said bore, means forsecurely holding said bearing blocks against movement within said shell,and a vertically and horizontally adjustable auxiliary bearing shoesupported by said. shell at one end thereof.

2. In a bearing for rotary shafts, a bearing supporting shell having arectangular bore, bearing blocks slidzt'bly seated in said bore andhaving bearing surfaces formed in their meeting faces, means for bindingengagement with said bearing blocks for hold- .ing them against movementwithin said shell, and a verticallyand horizontally adjustable bearingshoe supported by said shell at one end thereof.

In testimony whereof we afliX our signatures in presence of twowitnesses.
